BICYCLE-SADDLE.

SPECIFICATION forming part of Letters Patent No. 476,838, dated J' une14, 1892..

Application filed February 3, 1892. Serial No. 420,203. (No model.)

To all whom it may concern:

Be it knownthat I, FRANK SwEETLAND, a citizen of the United States,residing at Angola, in the county of Erie and State of New York,haveinvented a new and useful Bicycle- Saddle, of which the following isa specification.

This invention relates to improvements in that class of bicycle-saddlesknown as sus pension, and employed particularly in that class ofbicycles termed Safeties, though, as will hereinafter appear, thissaddle may be used upon the ordinary.

The objects of my invention are to provide a cheapand simpleconstruction of saddle capable ofuready adjustment, so as to increase ordecrease the tension of the same and adapt it for riders of variousweights.

Other objects and advantages of the invention will appear inthefollowing description, and the novel features thereof will beparticularly pointed out in the claims.

Referring to the drawings, Figure 1 is a perspective of a bicycleembodying my iinprovements. Fig. 2 is a longitudinal section of thesame. Fig. 3 is a detail of one of the sliding collars. Fig. 4 is asimilar View of the adjusting-screw. Fig. 5 is a side elevation of amodied construction of saddle.

Like numerals of reference indicate like parts in all the figures.

1 designates the inverted- L-shaped seatstandard of a Safety bicycle,though it may be the backbone of an ordinary bicycle.

2 designates a spring-bar oblong in crosssection, and at its middle isprovided with a depending stud 3, longitudinally bored, as at 4, so asto be adjusted upon the upper horizontal portion of the standard 1. Inthis position it may be secured by a binding-bolt 5, passing through theunder side of the stud and at its upper end binding against thestandard. At its center the spring-bar is provided with anupwardly'disposed bifurcated post 6. L-shaped adjustable collars 7 arelocated at opposite sides of the post 6. These collars are provided neartheir lower ends with spring-bar-receiving slots 8, and are adapted tofreely slide upon the spring-bar. At opposite sides of the slots 8 thecollars have perforations 9, and between the perforations the upper endsof thc collars are provided with recesses 10.

l1 designates the leather or seat portion of the saddle, and to theopposite ends of the same coiled springs 12 are secured. The terminalsor lower ends of the springs pass through and are secured rigidly withinthe perforations 9 of the front and rear ad j ustable collars. Atopposite sides of the recesses G the inner faces of the collars areprovided with transverse notches 13.

14C designates an adjusting rod or bolt, and the same is provided at itscenter with a plain cylindrical portion 15, which fits for rotationWithin the bifurcation of the post 6,while the opposite ends of the.same take into the recesses 10 of the collars. At opposite sides of thecenter the rod is threaded, the threads at one side being disposed tothe right and those at the opposite side disposed to the left. Atopposite sides of the plain bearin g portion 15, and therefore atopposite sides of the post 6, the rod is provided with polygonal bosses16, forming wrench-receiving portions, and their angles are arranged atvariance with each other, asy shown, so that in applying a Wrench one orthe other of the bosses may always be conveniently gripped. Between "thebosses and the sliding collars nuts 17 are mounted upon the rod, andeach is provided at radiallyopposite sides with cylindrical lugs ortrunnions 18, which are turned into engagement with the notches 13 ofthe movable collars.

From the foregoing description it will be seen that the spring-bar isfree to vibrate without bending the threaded rod or bolt 16, and that byrotating either of the bosses l5 or by rotating them alternately for thepurpose of convenience in gripping the sliding collars may be spread ordrawn together, and thus the tension of the seat 1l increased ordecreased and the saddle adapted for various riders.

In Fig. I have illustrated a slight modication, and the sameconsistssimply in extending the spring-bar 20 rearwardly and upwardlyand securing the same to the rear end of the seat, thus omitting therear slidingcollar 7 and employing only the front sliding collar 21,which is perforated to receive the front coiled spring 22, which isconnected at IOO its upper end to the sea-t or leather portion of thesaddle. The post 23 is transversely recessed, as at 24, as is also thecollar 21, and each has a transverse recess 25 to receive the threadedends of the tension-bar 26, the threads of which are oppositely disposedat the opposite sides of the centrally-located boss 27 of the same. Nuts2S are mounted on the ends of the rod at the inner sides of the post 28and the collar 21` and radially-oppo site trunnions 29, formed on thenuts, loosely fit in the recesses 24 of the post and collar. By rotatingthe boss 27 it Will be obvious that the collar may be moved from ordrawn toward the post and that the springs 2O and 22 may vibrateindependent of and without bending the tension-rod 26.

Having described my invention, what I claim, and desire to secure byLetters Patent,

l. In a saddle, the combination, with the spring-bar provided with apost having a bearing, a collar mounted for sliding on the bar at oneside of the post, said collar having a perforation and a transversegroove or seat in its inner face, a threaded rod journaled in the postand provided with a collar or angular boss, of the leatherseatconnections between its rear end and the spring-bar, the pair of springsconnected to the front end of the seat and having their lower endspassed through the perforations in the collar, and the nut 17, havinglugs 18, threaded on the rod and adapted to engage the seat of thecollar, substantially as specified.

2. In a saddle, the combination, with the spring-bar, the bifurcatedpost rising therefrom, the opposite collars mounted for sliding on thebar, the seat, and the oppositel pairs of springs connected thereto, ofthe right-andleft-hand-threaded rod mounted in the recesses formed inthe collars and having the plain central bearing portion located in thebifurcation of the post andl provided at opposite sides of the post withpolygonal bosses, the angles of Which are at variance With each other,substantially as specified.

3. In a saddle, the combination, with the spring-bar having upon itsupper side the bifurcated post and at its lower side the bored stud, theL-shaped standard, and the binding-bolt 5 for securing the stud thereto,ot' the opposite L-shaped sliding collars 7, having the recesses l0 intheir upper sides, slots 8 near their lower ends and oppositeperforations 9, the seat 11, the springs 12,.connected thereto andterminating in the perforations 9, theadjusting-rod 14, having the plainbearing 15, polygonal bosses 16, mounted in the bifurcated post andhaving its opposite ends threaded in opposite directions, the nuts 17,having the trunnions 18 at dialnetrically-opposite sides thereof andsea-ted in recesses 13 formed in the inner faces of the collars,substantially as specified.

In testimony that I claim the foregoing `as my own I have hereto affixedmy signature in the presence of two witnesses.

FRANK SWEE'ILAND.
